SCALE-BEARING.

SPECIFICATION forming part of Letters Patent No. 661,087, dated November6, 1900.

Application filed July 23, 1900.

T0 aZZ whom it may concern:

Be it known that I, WALTER B. STIMPSON, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Scale-Bearings, of whichthe following is a specification, reference being had therein to theaccompanying draw ings.

The invention relates to scale-bearings; and it consists in the peculiarconstruction of a pendent loop and a bearing-block secured thereto freeto have an independent swinging movement and which at the same time isheld from accidental displacement.

The invention further consists in the peculiar construction andarrangementof parts, as hereinafter described and claimed.

In the drawings, Figure 1 is a perspective View of a bearing. Fig. 2 isa vertical longitudinal section therethrough. Fig. 3 is a cross-sectionshowing a modified construction. Fig. 4: is an elevation of anothermodification. Fig. 5 is an elevation illustrating the manner ofassembling the parts, and Fig. 6 is still another modification.

The invention is especially designed for use in scales where agatebearing-blocks are desired. In the formation of such blocks the drillingof holes therein is an expensive and difficult operation on account ofthe extreme hardness and brittle character of the material. It hastherefore been found impracticable to pivotally connect the blocksbetween the supporting-loops. In my construction I obtain a pivotalsupport for the blocks without the necessity of drilling them, theconstruction being as follows:

A is a bearing-block, whichis preferably of substantially rectangularform and is provided with a bearing face a, preferably slightly concave,as shown. Upon the opposite side of the block A, opposite the face a, isformed a transverse notch or groove b.

B is a loop, preferably cut from a single piece of metal, so as to beboth endless and seamless. The width of this loop is sufficient toembrace the parallel sides 0 and d of the block A and'to thereby holdsaid block from endwise movement. The lower end portion of the bar eengages with the groove 1) and is rounded on its upper edge to permit ofa pivb'erial No. 24,619- (No model.

spread the sides of the latter snfficiently to allow the block to passbeneath the shouldersf, as shown inFig. 5. After the block is engagedwith the bar e in the grooveb the sides of the loop may be contracted orpressed inward, after which the block will be held from disengagementfrom the loop by the shoulders f.

In Fig. 3 I have shown the loop provided with bearing-blocks at eachend, which is intended to be used for the central connection between theplatform-levers, the construction being a mere duplication of that shownin Fig. 2.

While I deem it desirable to form an endless and seamless loop, this isnot absolutely essential, and, if desired, an open loop may be employed,such as is shown in Fig. 4, in which the opposite sides g and hembracethe parallel sides of the block A and the shoulder f on the side hholding the block from disengagement. Again, althoughI believe itdesirable that the shoulderfshould be arranged to prevent thedisengagement of the bar 2 from the groove 1), except by bending theloop, yet it is evident that said shoulder would prevent the block fromfalling out of engagement even if sufficient clearance were provided topermit of lifting the block, so as to disengage the notch from thepivot.

What I claim as my invention is 1. A scale-bearing, com prising a blockhaving a notch or groove on one face thereof, and a loop embracing saidblock having its end portion pivotally engaging said notch or groovesaid loop having a shoulder formed in its side projecting beyond theopposite face of said block and forming a stop for limiting the turningof said block on its pivot.

2. A scale-bearing comprising a block having a notch or groove on oneface thereof, and a loopetnbracing said block having its end portionpivotally engaging with said notch, said loop being provided on itssides with a shoulder projecting beyond the opposite face of said blockand arranged to pre= vent the disengagement of the pivotal portion ofsaid loop from said notch or groove but permitting of a limited freeturning of the block upon its pivot.

3. A scale-bearing comprising a substantially rectangular hlock having agrooved bearingface, a transverse notch or groove upon the opposite facethereof, and parallel side faces; and a loop embracing said paral- I5lel side faces having one end portion pivotall y engaging with saidtransverse groove and a projecting shoulder overlapping saidbearing-face whereby said block is free to swing upon its pivot througha limited angle but is prevented from disengagement from said loop.

In testimony whereof I affix my signature in presence of two witnesses.
